Resounding Sagittarius Crimson

#c01209
Notes

Resounding Sagittarius Crimson (#C01209) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (3°, 91%, 39%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Latin sagittarius, archer-of-the-zodiac. As a color modifier, sagittarius implies a centaur-archer-and-fire-sign-and-Jupiter-ruled-mutable-fire quality, the visual register of Hellenic-Sagittarius-and-Chiron-centaur-archer hand-centaur-archer-and-fire-sign-and-Jupiter-ruled-mutable-fire Hellenic-Sagittarius-and-Chiron-centaur-archer-and-galactic-center sagittarius-and-centaur-archer-and-fire-sign surfaces under Hellenic-Sagittarius-and-Chiron-centaur-archer-and-galactic-center late-autumn-and-November-and-December mutable-fire-sign-light.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
